I'm struggling with performance issues on a 300ms network link. Do anyone g=
ot a suggestion on how to tune this to its best?
We have wan accelerators but they do nothing for UDP packages. Currently it=
 takes 7 minutes to transfer a 34M file :-/

I have tried to adjust udpsize and rxpck on the server and chunksize on the=
 client. I can see ACK packages with out of sequence and wide gaps of time =
in the conversation when I analyze it in wireshark.

Best regards
